These tiny brushed DC gearmotors have a diameter of just 6 mm and weigh just over a gram, which makes them great actuators for miniature robots and incredibly small mechanisms. They consist of a coreless electric motor fastened to a planetary gearbox by a small clip. The gears are made from liquid crystal polymers (LCPs), and gearbox’s nylon result shaft is compatible with our 14 mm wheels. Three gear ratios can be found:
26:1, which has a free run speed of 2500 RPM and stall torque of 1 1.5 oz-in (110 g-cm) at 6 V
136:1, that includes a free run speed of 500 RPM and stall torque of 8 oz-in (550 g-cm) at 6 V
700:1, that includes a free run velocity of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Note: Stalling or overloading gearmotors can greatly reduce their lifetimes and even result in immediate harm. For these gearboxes, the suggested upper limit for instantaneous torque is definitely 3.5 oz-in (250 g-cm); we strongly advise keeping applied loads well under this limit. Stalls may also result in rapid (possibly on the order of seconds) thermal harm to the electric motor windings and brushes; a general recommendation for brushed DC engine operation is 25% or much less of the stall current.
The intended nominal operating voltage for these motors is 3 V to 6 V, though generally, these kinds of motors can be used at voltages outdoors this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages may not be practical, and higher voltages could start negatively influencing the life span of the electric motor. When operating at 3 V, the free-run acceleration, stall torque, and stall current will all end up being approximately half of what they are at 6 V as these specifications scale roughly linearly with voltage.
Because the gearmotor’s output shaft is nylon, there may be small variances in the diameter from unit to unit. These variations may cause press-suit attachments like our 14 mm wheel to match loosely in some instances. In the event that you experience a loose fitting, you could try swapping wheels or using a small dab of glue to greatly help contain the wheel on.
The next diagram shows the micro plastic gearmotor dimensions in mm. The planetary gearbox includes a D-shaped plastic output shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” portion of the shaft is 2.5 mm long. The electric motor actions 6 mm in diameter and 9.3 mm in length, and the gearbox size, labeled “L” in the diagram below, depends upon the gear ratio.
26 RPM Planetary Gear Motor with encoder: compatibility
This small 12V motor includes a magnetic encoder mounted prior to the gearbox for a much better resolution. Its 4 mm output shaft makes it compatible with lots of ep mounts and component, including clamping hubs, Planetary motor mounts, in addition to 4 mm toothed wheels and pinion gears.

Spur Gear vs. Planetary Gear
The two most common setup of DC motor gearbox are spur and planetary. Spur type gearbox are simpler, less expensive, and work greatest for low torque applications. Torque capability of spur type gearbox is limited because each gear in the train bears different load. Planetary gearboxes, on the other hand, share equivalent load over multiple gears, making them more durable for high torque software.
